Typically, we regularly have carried out a technical review to know a progress status and outcomes of a project to the appropriate technical plans. But during the technical review executed at a planned point of time, lots of problems; reports of an ambiguous progress status and outcomes, a discordance between opinions, and an hour's delay, have been occurred. To solve those problems an early stage, an informal reviews are executed before the formal technical review. One of the informal review is the Peer-Review. This paper is a matter of the effective and efficient Reer-Review process utilized in performing the national research and development project. Additionally, it was presented a general misunderstanding and improvement plan about the Peer-Review.

The purpose of this study was to evaluate the effect of concentration and pH of lactic acid on the formation of artificial root caries lesions formation in bovine teeth. The characterictics of artificially produced early root lesions were observed with polarized light microscope and the depth of lesions were mearsured with measuring microscope The results were as follows: 1. In the group of low pH and high concentration of lactic acid, the progress of lesion formation was faster than that of high pH and low concentration lactic acid group. 2. In the same group, initial lesion progress faster, but progression rate was reduced as time goes by. 3. In the development of initial root caries, cementum was act as a barrier to protect dentin from lesion progression.

Most payments in domestic construction are issued in lumpsum unit price contracts according to the completed construction rate. This method generates problems in losing time and increased costs for the owner and contactor. In overseas projects, payments are issued in accordance to completed milestones. The milestones themselves base on the original schedule and allow effective schedule management on the tasks. In domestic construction, however, introduction of milestone payments requires enhanced management capability of owners and contractors. Hence, this study investigating how to activate schedule management devices to analyze progress payments in domestic construction.

In 2007 SeeReal had demonstrated the first large realtime holographic 3D display based on tracked viewing windows. Subsequent work has lead to advanced concepts for overcoming limitations of the prototype. This paper describes the current state of SeeReal's developments and its progress in practical realization of these advanced solutions.

Arresters are the best protective device on electrical power systems against transient overvoltages generated by lightning and/or switching operation. Nonetheless, arresters are deteriorated by absorption of moisture in the environments of its use, repetition in the protective operation to overvoltages, and some defects at manufacturing. It is therefore important to estimate the electrical characteristic changes of ZnO blocks. In this paper, an accelerated ageing test by a standard lightning impulse current was carried out to extract parameters needed for arrester diagnosis, and leakage current components were measured. Total energy applied to the ZnO blocks at each time is about 1,050[J] in 8/20[${\mu}\textrm{s}$] impulse current. From the experimental results, we proposed electrical parameters and leakage current level to diagnose arrester soundness.

Mobile nodes in MANETs have the nature of unrestricted mobility so that they will join and leave the network frequently. Therefore, it important consideration to determine the optimal distance progress between relaying nodes along the route in order to maintain the established route for an arbitrary length of time (i.e., route duration). In this paper, we derived the link maintenance probability by considering the initial distance between two relaying nodes and node mobility. Based on the link maintenance probability, we further analyzed the route stability by considering the impact of distance progress between relaying nodes along the route.

The construction of green building has distinct charicteristics by work classification by applying green technologies. Thus if the new technologies are applied to construction, unskiiled worker can experience construction time delay, reconstruction occurrence and quality decrease because of mistakes during the construction and work progress. For this background, we establish the work progress manual to secure quality and performance during the construction phase of green building and provide method to be used in the construction sight operation.

In this Paper, systematic quad-tree array method for easy composition is proposed, which is based on music cord. The appearance of the computer composition system, so called MIDI, expects that non-musicians can make musics easily, but, in fact. non-musicians still compose hard. This approach shows that a computer makes cord progress through a database, which in-putted all practicable cord progress. Experimental results showed that this method is superior to conventional method such as. composition time as well as that of method.

In this study, the heart rate variability(HRV) signal of operating patient was acquired according to anesthesia progress and identified to evaluation possibility of depth of anesthesia in each anesthesia stage. The HRV signal was analyzed time-frequency domain applied to Wigner-Ville distribution method, the characteristic parameters were extracted for evaluation of depth of anesthesia in each anesthesia stage. The progress of general anesthesia was divided into the states of pre-operation, induction of anesthesia, operation, awaking and post-operation.

In the development process, the objective of a reliability growth program is to track the increase in system reliability, and determine as early as possible whether or not the system reliability is growing at a sufficient rate to meet the required goal and allocate available resources accordingly. Implementation of this kind of program will provide very useful information on concept selection, product/process reliability, and cost effectiveness without too much time, money and engineering effort being spent on the development of failure suspect parts. The purpose of this research is to present a practical method for efficiently monitoring a reliability growth test process using AMSAA(Army Materiel Systems Analysis Activity) reliability growth model. The presented growth management is a viable method for identifying failure modes, incorporating design changes and monitoring reliability progress on an on-going basis during the early stages of a product development program.
